Abstract
(Current Biology 31, 4773–4787.e1–e8; November 8, 2021) Since publication, we have identified minor errors in Table 1 and Figure 1B. First, during the manuscript revision we made minor changes to reconcile our species dataset with the published IUCN Red List status of four species and changes to the habitat classification of seven species. While the changes were propagated into the manuscript text, graphs, and statistical analyses, they were not propagated into Table 1. Second, an error in Figure 1B arose due to the default sampling for symbology in the GIS software. When determining the range of values to use for the symbology of the figure, the software did not query all the hexagonal cells and their species counts by default, missing some of the richest cells on the South Africa/Mozambique border, which were not included in the original visualization. The corrected figure now has the true range of Data Deficient (DD) species richness and includes all hexagonal cells with all values. Now the maximum number of DD species per hexagonal cell is 15 rather than 9 as originally reported, which is still much lower than the maximum of 55 reported in 2014. Both errors have been corrected online. The authors apologize for these errors and any confusion that may have resulted.Figure 1BCurrently, over one-third of chondrichthyans are threatened (original)View Large Image Figure ViewerDownload Hi-res image Download (PPT) Overfishing drives over one-third of all sharks and rays toward a global extinction crisisDulvy et al.Current BiologySeptember 6, 2021In BriefThe IUCN Red List of Threatened Species is increasingly used to reveal the health of ocean biodiversity. Dulvy et al. assess 1,199 chondrichthyans and demonstrate the need for fishing limits on target and incidental catch and spatial protection to avoid further extinctions and allow for food security and ecosystem functions.
